2021-18: GRAPHENE AS A SENSOR FOR THE ELECTRONIC PROPERTIES OF FEW ATOM CLUSTERS
2D sensing platform for atomically precise clusters
Focus: nanofabrication, cluster deposition and electrical characterization under extreme conditions (i.e. low temperatures and high magnetic fields) Required background: For this position we are searching for an excellent and highly motivated candidate with a Master degree in Physics (or equivalent) and with interest in solid state physics, chemical physics, and quantum mechanics. The candidate should master english.
Supervisors:  Joris Van de Vondel  and Ewald Janssens

Summary:

When merging atoms into a cluster, the unity is not simply the sum of its parts. Indeed, by bridging the gap between a single atom and a bulk material one observes a strong size dependence: At this length scale every atom counts! The emerging properties of these clusters combined with their preserved atomic-like character sparked researchers to call them superatoms.

Despite the ultimate small size, these superatoms can be fabricated using conventional sputtering techniques and size selected, with atomic precision, using mass filters. At this point one can ask the question:  Why are these superatoms never used as basic building blocks to create novel functionalities, i.e., implemented in a real device architecture?  The answer to this question is straightforward: contacting a zero dimensional object seems impossible without destroying its intrinsic properties.

In this project, we make it happen by introducing a unique approach, using the two-dimensional material graphene as a 'smart' landing platform for the fabricated clusters. Clusters land without strong modifications, converting these superatoms into superdopants. At the same time, the graphene can be used as a local sensor for the cluster properties. This fascinating synergy allows us to perform material engineering with ultimate precision and explore size specific charge transfer and the catalytic properties of few-atom clusters through electronic readout of a graphene-cluster hybrid structure.

This project is mainly an experimental work using state-of-the-art nanofabrication and characterization tools: clean room facilities (electron beam lithography), cluster deposition and electrical characterization under extreme conditions (i.e. low temperatures and high magnetic fields).
